Functionality

IMPORTANT NOTE: This function was introduced in v0.7.0 because of a change that the jQuery team made in jQuery 1.7. See my blog posts
here and
here for details. If you are using a version of SPServices prior to v0.7.0, you do not have this function.

Can be used to find namespaced elements in returned XML, such as rs:data or z:row from GetListItems.

My hope is that by having this function in place, SPServices will be a bit more future-proof against changes made by the jQuery team. The function is only required if you want your script to work reliably cross-browser, as Internet Explorer will reliably
find the elements with the simpler .find("z:row") syntax.
